p-Toluenesulfonic acid catalyzed rapid and efficient protocol for one-pot synthesis of α-amino nitriles
A simple, rapid and efficient practical method for one-pot synthesis of α-amino nitriles has been achieved by a threecomponent condensation of carbonyl compounds, amines and trimethylsilyl cyanide in the presence of p-toluenesulfonic acid (p-TsOH) as a catalyst at ambient temperature. Operational simplicity, economic consideration, high yield, short reaction time and low toxicity are the key fe...
متن کاملAn efficient one-pot synthesis of α-amino nitriles using ecofriendly Lewis-acidic ionic liquid choline chloride.2ZnCl2
α-Amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2ZnCl2 as a bio Lewis acidic ionic liquid. Mild Lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.

متن کاملEfficient one-pot synthesis of pyrazoles catalyzed by nano-crystalline solid acid catalyst
An efficient and green protocol for the synthesis of pyrazoles derivatives by one-pot reaction of different 1,3-dicarbonyl compounds with hydrazines/hydrazides has been developed using nano-sulfated zirconia, nano-structured ZnO, nano-g-alumina and nano-ZSM-5 zeolites, as the catalyst. The optical properties of the nano-structured catalysts and organic molecules were studied. The advantages of ...
